Brad Cohen, on whom film Hichki is adapted, talks about his struggles as an outcast kid in school.

Motivational speaker Brad Cohen whose story has inspired Bollywood film Hichki said that though he was an outcast as a child, he never gave up and faced it all with courage. Sharing his story with the media on Monday from Atlanta, Brad said, "I was 10 years old when the medical condition started and I knew that I am different. But my mother never made me feel like one because she said if you have a positive attitude you can win the battle. Growing up with Tourette syndrome was not easy. I was always pushed into a corner."

He went on adding that his teachers gave up on him when he was a kid, "nobody trusted my potential. But I knew that I will be a teacher when I grow up. That time I wanted to tell everyone whether you are dealing with Tourette syndrome or any other challenges in life there is a way to face them and not to give up."

What prompted him to write a book? "In my childhood, nobody understood me in school. My teachers had no confidence in me and that used to affect my confidence. Now that I learnt to overcome my challenges in life, I want to stand by my every student and other people who are facing any kind of disorder that is creating an obstacle in their lives," Brad said.

Rani Mukherjee is seen playing the role of the teacher suffering from Tourette syndrome according to him, he was quite surprised to know that, asked about if he watched any of Rani's film, he said, "Yes I watched one film where she played a role of a disabled girl (referring to her film Black), and the way she performed I realized she is very empathetic towards others."

Before shooting of the film, Brad had a candid chat with Rani and the director of the film Siddharth P. Malhotra who has been working on it for last five years.
